Since the first practical organic light-emitting diode (OLED) was developed in 1987 by Ching W. Tang and Steven A. VanSlyke at Eastman Kodak Company in the U.S., OLED technology has come a long way. The original device used two thin organic layers to produce green light when electricity was applied, demonstrating that organic materials could be used to create practical light-emitting devices. Today, OLEDs are widely used in smartphone and television displays as well as lighting, with continuous improvements in efficiency and lifespan.
